Hello all I am new here. I am trying to install a fan timer for the bathroom, but all 4 switches in the box are all wired on switch loops. the attic is above the room so i am able to crawl up there, but I am curious as to the best way to wire it in this situation. I have not been able to find out information on wiring a timer when a switch loop is used. Any advice would be much apreciated.
